BMW tuner par excellence Alpina is returning to the motor racing scene for the first time in two decades with the new B6 GT3, which the pseudo-works firm unveiled for the first time here at the Geneva Motor Show. Based on the 6 Series, the B6 GT3 features a unique radial supercharger fitted to its 4.4-liter V8 to drive 530 horsepower to the rear wheels - in proper Bavarian style - in what looks to be a compelling competition package.

Alpina itself will be fielding a pair in the European FIA GT3 series and at "selected 24-hour endurance races" (Nurburgring, Le Mans... we're looking at you), but the B6 GT3 will also be offered to private teams. Alpina has fitted adjustable everything to the car and a full array of electronic control systems to ensure that gentlemen racers - not just professional drivers - will be able to handle it and so that the car will qualify for a wide array of racing series. We're looking forward to seeing the green menace tackling the Green Hell soon, but in the meantime had to content ourselves with checking it out at Alpina's show stand here in Geneva where it was displayed alongside the new B7 Bi-Turbo, which we'll have for you shortly.
